An Amazon user receives an email that says a recently-placed order wasn't processed. The message may say something like this: "Amazon is having issues with your order. You will not be able to access your account or make future purchases until we confirm your password and login email address. Click here to confirm."

If you click on the (fake) login button, you'll be redirected to an Amazon page that appears trustworthy. Before you enter any personal data, check the site's web address. The fraudulent domain likely has nothing to do with Amazon or may be a slight variation of www.amazon.com.

Once you fall victim to the scam, you'll be led to more pages that ask for sensitive information under the guise of account verification. Data like your credit card account number, Amazon password and home address may be passed onto criminal third parties.

"If you received correspondence regarding an order you didn't place, it likely wasn't from Amazon.com," the company warns on its website.
